[Xorp-hackers] XORP OSPF routing table

[Raluca Blidaru]

Hi Ben,

I have used the 1.8.3 version from github and compiled XORP source package on Ubuntu.

 With regard to xorpsh, I can print the routing table (show neighbours), but is it possible also to add/modify any entry from there, or I have to develop myself the interface for this? Should I be aware of any XORP design constraints, in order to include my commands into xorpsh?

The routing tables from the OS, can they by imported into XORP router?

Thanks,
Raluca

The idea is to use an open source software router and access directly the routing table in memory/temp file, modify it by adding/changing routing entries and see how the information is propagated into a testing lab network.

Is there already a built-in interface to read from the temp files created if there is where I have to look for the routing tables? Are these files saved in a readable format? If not, how I can access the OSFP routing table for the purpose I described before?

The routing tables are all in RAM in the OSPF process, except for the routing
table(s) in the OS's kernel.

You can use xorpsh to print out the various routing tables and could parse that
if you wanted.

OSPF has a timer bug in the latest stable build, so please use the latest code
from github until I get a chance to release another build.

Thanks,
Ben
